Abstract

To improve the CNG engine injector nozzle hole geometry and to understand the processes involved in fuel-air mixing and combustion is a challenge. Improvements the injector nozzle holes geometry can be improve the fuel spray distribution in the combustion chamber. This research has been improvements to the fuel spray distribution in the combustion chamber with proper new injector nozzle holes geometry to create turbulence, in addition to modifying the angle of CNG fuel spray. The modelling fuel spray distribution of the original injector nozzle compared to the new injector nozzle with multi-hole geometry in the CNG engine shown in this research. The conclusion of this modeling has been shown in this study that the new injector nozzle holes geometry can be increase the fuel spray distribution in the CNG engine cylinder.
